How to sync & quickly reinstall applications on ubuntu

Being new to Linux and to Ubuntu, I’ve taken quite some time to tune it to my needs on my netbook. As I’m now convinced by the OS, I plan to install it on my desktop in the next few days. I was hoping that with Ubuntu One, after a sync, I would find back all my settings on the newly installed machine : system settings, language, list of installed programs (to quickly reinstall the same set), email chat and microblog accounts, Unity launcher shortcuts, etc.

I’ve just read trought the Ubuntu One website and it seems such a settings-sync feature is not part of it. Is this something that could be done? Is it planned? Is there another way to achieve this same effect?

Thanks in advance for any infos on that.

Ubuntu One does not currently support settings sync of arbitrary applications, although we’re asked for it a lot. There are a couple of reasons for this. The major one is this: applications need to be written with settings sync in mind. If you take an arbitrary application, which stores its data in a configuration file, then that application is extremely unlikely to notice if Ubuntu One changes that configuration file while the application is running. Indeed, the app will almost certainly overwrite any Ubuntu One-made changes if you change the configuration of the app yourself.

A second issue is that applications do not distinguish between machine-specific settings and user-specific settings. If, for example, your app remembers the last files that it loaded, and you sync that list of recent files with Ubuntu One, what should other instances of that app (on other computers) do if those files are not present? If you save the app’s window’s position on your huge monitor, and then sync that setting to your netbook, how does the app cope with that? All of these things are certainly handleable within the app, but many apps don’t actually realise that they may need to handle them.

The issue here is not that settings sync is in itself hard, but that applications are not really built with the idea that the settings file may contain “impossible to create”, unlikely, or contradictory settings, and that the settings file may change at any time.

Some applications are set up to deal with this, and as part of the Ubuntu One application developer programme I’d be happy to talk to any application developer who would like their app to have syncable settings, to work out how best to do it for that app.

  I’m planning to reinstall my OS by not formatting my root partition (I only use a single partition) as this will preserve the contents of my home directory, but the problem is that when I’ve done it in the past, it’s wiped all my third party applications, and I was wondering if there was a way I could back up and restore them afterwards.

  You can do this in the synaptic package manager (System->Administration) Make sure your selection is in the “All” section then go to File->Save markings, make sure you check mark “Save full state, not only changes” then save (somewhere where it won’t be formatted 😉

  When you are done installing you can go to File->Read markings

  Most of your programs will download, except the ones which you added a repository for (well at least until you re-enter them). You might have to fix some of the broken packages in synaptic after as well.

  I’m sure someone else might now how to backup and restore the sources list..

  A lot depends what kind of installing methods 3rd party software is offering.

  To help out re-install of those 3rd party software you should

  Take copy of apt-get repositories ( /etc/apt/sources.list ) for 3rd party repositories. Example spotify and virtualbox provides repositories for installation.

  Copy all .deb’s and zip’s/tar.gz packages on your hard-drive (I usually find them from my home folder either Downloads or Software, could be something else on you). But usually benefit of this depend how fast connection you have and wether or not that version uses deprecated functionalities no longer provided by new version.

  Crawl down your applications menu and write up all 3rd party software you want still to find from your new system and write that down to paper.

  I understand that OneConf is tool which one of goals will be to make this easier. Might be worth keep and eye on development.

  The “enabled” and “active: running” in the output shows that Cockpit has been started successfully.

  Access Cockpit Web Console

  Cockpit listens on 9090 TCP port. Thus we need to allow the 9090 port in the firewall for this service to work.

  To allow the 9090 port in the OS firewall, run the following ‘ufw’ command.

  Now access Cockpit web console using the following URL:

  Use the root credentials or sudo user credentials to log in.

  The main page section shows us some information about the machine we are running on, as the hardware, hostname, operating system, and system time.

  Conclusion

  In short, the Cockpit web console provides a graphical overview of the core components and overall status of a Linux machine. Today, we saw how our Support Engineers install the Cockpit web console on Ubuntu.
